Health professionals should not be forcing the terminal patient into preestablished stages, but rather should take into account the actual experiences of the individual. The purpose of this study was to identify the defining characteristics of the dying process within the terminal phase. A retrospective audit of 11 deceased clients' charts from a hospice program was conducted. Each client had been diagnosed with terminal cancer. Defining characteristics of the process of dying were delineated and organized into groups of subjective and objective phenomena. These included anorexia, absence of pain, nausea, vomiting, tachycardia, respiratory status, withdrawal of self, secretions, mental status, urinary output, restlessness, bowel sounds, blood pressure, internal temperature, skin temperature, skin color, edema, and diaphoresis. Although the sample size was small, these findings confirmed that the dying process for terminal cancer patients was an individualized experience. Additional research is needed to build on this framework.

Benzodiazepines have so many uses in cancer patients that the physician may target more than one advantage as he considers choice of drug and dose. Nausea, pain, and anxiety may be treated simultaneously. Since these patients are often taking a number of medications, the simplest regimen has the most benefit. These drugs treat reactive anxiety, insomnia, claustrophobia, and panic disorder. As they treat anticipatory anxiety and phobia, they mitigate anticipatory nausea and a component of post-treatment nausea. With chemotherapy itself, they cause sedation, suppress recall of treatment, limit vomiting, and are seen as desirable by patients. They suppress the restlessness associated with metoclopramide and other dopamine-antagonist antiemetics. The analgesic effects are best seen in conditions of high anxiety, muscle spasm, and deafferentation syndromes. The advantages of sedative and antipsychotic effects may be exploited to suppress the psychiatric complications of high-dose corticosteroids.

Ondansetron was compared with metoclopramide for antiemetic efficacy in a randomised double-blind trial in 122 patients with advanced breast cancer. All patients were treated with epirubicin (greater than 50 mg/m2) and cyclophosphamide (greater than 500 mg/m2). 50 patients receiving ondansetron and 60 with metoclopramide were considered evaluable. Ondansetron was at least as effective as metoclopramide in the control of vomiting and nausea. The percentage of patients with complete plus major control was 72% (59-85%) vs. 61% (48-74%) on day 1 (P = 0.230) and 79% (67-91%) vs. 66% (53-78%) on days 2-3 after chemotherapy (P = 0.122). Over the 3-day study period, nausea was absent or mild in 60% of the patients treated with ondansetron, compared to 45% given metoclopramide (P = 0.064). No major drug-related side-effects were reported. 1 patient receiving ondansetron experienced gastrointestinal disturbance and headache. Episodes of diarrhoea, fever, hyperkinetic syndrome, fatigue, restlessness and migraine with vomiting were reported by 5 patients treated with metoclopramide. None of the changes in the biochemical or haematological parameters was attributed to the antiemetic treatments.

During 1984-1989, 19 Bedouin children, 4-8 years old, were hospitalized because of henbane plant (Hyoscyamus reticulatus) poisoning. There were 14 cases in the autumn, 3 in the spring and 2 in the summer. The most prominent signs were altered state of consciousness (including deep coma in 3) and flushed dry, warm skin in all. Pupils were dilated in 18 of the 19 and restlessness and hallucinations were present in 17. Less common were vomiting, increased tendon reflexes, convulsions, involuntary movements, ataxia, hypertension, hyperpyrexia and tachycardia. Therapy included intravenous physostigmine in 7 and sedatives (diazepam and triclofos) in 6. All were free of symptoms within 24 hours of admission. Henbane may grow as an annual or biennial. Renewed growth of leaf rosettes occurs before the first rains and they attract attention in the fields. The parts of the plant eaten by most of the children were the roots, which are easily mistaken for the edible roots of other plants. The main alkaloids in henbane are atropine (hyoscyamine) and scopolamine (hyoscine) which explains the clinical picture of mixed stimulation and depression of the brain. Educational measures should be undertaken to prevent poisoning of Bedouin children by eating such plants.

1. The authors review the literature describing acute symptomatology produced by the gradual or abrupt withdrawal of heterocyclic antidepressants, monoamine oxidase inhibitors (MAOI) and neuroleptics. 2. Withdrawal of heterocyclic antidepressants and antipsychotic agents causes similar symptomatology. Symptoms produced by the discontinuation of these drugs include nausea, emesis, anorexia, diarrhea, rhinorrhea, diaphoresis, myalgias, paresthesias, anxiety, agitation, restlessness, and insomnia. 3. Psychotic relapse is often presaged by anxiety, agitation, restlessness, and insomnia. Prodromal symptoms are distinguished from the effects of neuroleptic withdrawal by a temporal relationship of the latter to reductions in the dosage or discontinuation of antipsychotic agents. 4. Withdrawal of MAOIs can result in severe anxiety, agitation, pressured speech, sleeplessness or drowsiness, hallucinations, delirium, and paranoid psychosis. 5. MAOI withdrawal phenomena resemble the symptoms produced by the discontinuation of chronically administered psychostimulants. 6. The capacity of MAOIs to exert amphetamine-like effects presynaptically and the propensity of somatic treatments for depression to subsensitize presynaptic receptors regulating the release of catecholamines provide a basis for the development of psychotic symptoms upon the withdrawal of MAOI. Evidence for this hypothesis is reviewed.

This randomized, double-blind study evaluated the antiemetic efficacy and the side-effects of promethazine pretreatment (0.5 mg.kg-1 IV + 0.5 mg.kg-1 IM) versus droperidol + placebo pretreatment (droperidol, 0.075 mg.kg-1 IV + physiological saline, 0.02 ml.kg-1 IM). One hundred unpremedicated ASA physical status I children ranging from two to ten years, and undergoing outpatient strabismus surgery were studied. All children received inhalational anaesthesia with halothane, nitrous oxide and oxygen. Neither opioids nor muscle relaxants were used. The incidence of vomiting and/or retching and the incidence of side-effects were determined in the post-anaesthesia recovery room (PARR), in the short-stay surgical unit (SSSU), and after discharge from the hospital (including the journey and the stay at home during the first postoperative day). Promethazine and droperidol were equally effective in reducing the incidence of vomiting before discharge to two and eight per cent respectively. On the contrary, the incidence of vomiting after discharge and overall were significantly less with promethazine (ten and ten per cent) than with droperidol pretreatment (54 and 56 per cent) (P less than 0.0001). Promethazine permitted the time to discharge from the hospital to be reduced to an average of three hours, without increasing the incidence of vomiting postdischarge. Promethazine pretreatment is much less expensive than droperidol pretreatment. The incidence of restlessness was significantly less with droperidol (eight per cent) than with promethazine (36 per cent) (P less than 0.001). Promethazine pretreatment demands the use of an analgesic like acetaminophen in order to reduce the incidence of postoperative pain and restlessness.(ABSTRACT TRUNCATED AT 250 WORDS)

Propofol or methohexitone was given to the same twenty patients on two separate occasions during total intravenous anaesthesia for microlaryngeal surgery. With propofol the quality of induction was superior. Fewer patients required supplementation. Heart rate and blood pressure were well controlled at levels of 110-120% baseline. There were fewer side-effects during maintenance and recovery. Patients were able to return home earlier. However, apnoea and pain on injection occurred frequently, the latter when injection was made into the dorsum of the hand. With methohexitone, apnoea, abnormal movement, nausea, vomiting, headache, restlessness and confusion were common. Cardiovascular variables were poorly maintained at levels of 170-180% baseline. The results suggest that propofol is suitable as the sole anaesthetic agent in patients undergoing microlaryngeal surgery.

Plasma immunoreactive cationic trypsin (ICT), which is a specific and highly sensitive indicator of pancreatic injury, was measured in 14 children with signs of systemic envenomation following a sting by the scorpion Leiurus quinquestriatus. High ICT levels were found in 13 children (93%), indicating that acute pancreatitis is a common complication of envenomation by this scorpion. The pancreatitis may account for the abdominal pain and vomiting commonly seen in scorpion envenomation and may also contribute to the agitation and discomfort noted in young children.

One hour after suicidal ingestion of about 20 mL of a 38% solution of bromofosmethyl, CAS: 2104-96-3 (bromophos), a 52 year-old female was admitted to the hospital with extreme miosis, hypersalivation, hyperperistalsis and muscular fibrillation. Gastric lavage was performed and activated charcoal administered. Cholinergic symptoms were antagonized by repeated doses of 0.5 mg atropine. Because of the high dose of bromophos, hemoperfusion was performed with amberlite XAD4. The bromophos clearance during hemoperfusion was 95 mL/min (flow 200 mL/min). The patient received two doses of 500 mg obidoxime for recurrent muscular fibrillation. The further clinical course was uneventful. On day 4, the patient was transferred to a psychiatric ward because of persistent suicidality. In contrast to poisoning by most organophosphates, red blood cell acetyl cholinesterase was only minimally depressed but the plasma butyryl cholinesterase was initially decreased and normalized within a few days. The records of 25 patients reported to our Poison Control Center with ingestion of more than 1 g bromophos were also evaluated. The most frequent symptoms were miosis, hyperperistalsis, hypersalivation, agitation, nausea/vomiting and convulsions. Nine of the patients had no symptoms. Bromophos is relatively less toxic than its phosphate derivative, parathion.

Thirty-seven patients with retinoblastoma were evaluated prospectively by clinical examination, lumbar puncture, and CT. Eight (22%) of the 37 were found to have meningeal dissemination. The tumor was bilateral in three patients. Two cases showed no CT signs of local recurrence. Headache, nausea/vomiting, and restlessness were the most common symptoms. CT scans in these patients showed diffuse meningeal contrast enhancement, nodular masses, ependymal-subependymal enhancement, and ventricular dilatation. Our series of eight patients with meningeal spread illustrates a considerable range of dissemination patterns referable to retinoblastoma. One case illustrated the CT finding of multiple epidural metastases.
